BUCKLE or. ELAsTIc LINK.

Specication of Letters Patent. Patented Aug. 30, 1910.

' Application filed July 26, 1909. Serial No. 509,671.

To all whom Lt-may concer/n.: l

Be it known that I, JOHN J. JACOBS, a citizen of the -United States, residing at New York, in the county of New York and State Vof New York, have invented certain new and useful Improvements in Buckles or Elastic Links, of which the following is a back of lthe frame 1.

specification, reference being had therein to the accompanying drawing.

My invention relates especially to the construction and arrangement of buckles for belts and the like, and has for its object the provision of such buckle, wherein an elastic link is provided which will permit a material variation in the length of the belt while at all times maintaining the requisite tension to keep the belt in proper position.

To attain the desired end, my invention consists incertain novel and useful combinations or arrangements of parts, and peculiarities of construction and operation, all of which will be hereinafter first fully described` and then pointed out in the claims.

In the drawing, Figure 1 is a rear elevation of a belt buckle embodying my invern,- tion. Fig. 2 is a like view showing thc spring mechanism as partially compressed, permitting elongation of the belt. Fig. 3 is a vertical, sectional view at line ai-a of Fig. 1. Fi 4 is a cross-sectional view at line 5-b of Fig. 1. Fig. 5 is a view of the elastic link removed from the front piece of the buckle. Fig. 6 is a perspective view of a modifiedv form of arrangement of the spring mechanism.

Similar numerals of reference, wherever they occur, indicate corresponding parts in all the figures.

1 is a frame or buckle-front, preferably made of zmetal.`

2 is a back-'piece inade of leather, or any other appropriate material for closin the opening in the frame 1, but if desire the front of the buckle may be made entirely of metal.

3 is a cross piece secured to one end of the Extending longitudinally of the buckle from the cross piece 3 are guide rods 4.

5 is a of a buckle ory any other member it is desired to engage.

6 is a cross bar provided with eyes 7 arl ranged to engage the bars 4. y 8 are spiral springs embracing the rods 4. 9 is a belt, made of leather, webbing, ribyoke for the reception of the claspv bon, or any other desirable material, se# cured to the cross bar 3, passing therefrom around the bar 6, and back beneath the bar 3. By this peculiar arrangement the material 9 can lengthen twice the length of the compression of the spring mechanism, as it is secured tothe ixed bar 3, and passes around the movable cross-bar 6, over which it plays as the spring mechanism contracts -and expands.

When itis desired to use my device to take the place of elastic webbing in suspenders, and the like, the front partjof the buckle may be dispensed with, and the rear` portion of the mechanism as illustrated in Fig. 5 employed.

The modification of Fig. 6 shows a single spring and guide rod, and such construction does not depart from the spirit of my invention.

My device will be found admirably adapted to the uses and purposes for which it is intended, as it entirelydispenses with elastic webbing, which is liable to rapidly deteriorate with age and use, while possessing all the advantages of such webbing.

Having now fully described my invention, what 4l claim as new therein, and desire to secure by Letters Patent, is:

1. An elastic link in which is comprised a front portion or frame having an opening, a closing for said opening secured to the back of the frame, a movable bar mounted at the rear of the frame upon suitable guide mechanism which is lixed to the frame, said guide mechanis1n,belt material secured to the frame at the end opposite tothe movable bar and loosely passing around said bar, `and spring mechanism engaging said bar and frame, substantially as shown and described.

belt material loosely passing around said movable member, the end of the belt material being secured to the frame, substantially as shown and described.
